| Abstract Scope |
WTaTiVCr High-Entropy Alloys (HEAs) are recognized as promising candidates for fusion plasma-facing applications. However, the environmental impact of their development and fabrication methods remains insufficiently characterized. This study presents a comparative evaluation of two powder processing routes: mechanical alloying (MA) and low-shear 3D mixing. Both fabrication methods yield single-phase, Body-Centred Cubic (BCC) WTaTiVCr HEAs with comparable Vickers hardness and relative densities exceeding 98%. Applying a “cradle-to-gate” (i.e. from raw material acquisition to arc plasma sintering) Life Cycle Assessment (LCA) method, the carbon footprint of each route mentioned is estimated. The findings identify the more environmentally friendly route as well as carbon footprint “hotspots” in each process. Results provide quantitative information useful for decision-makers in process selection and optimization. |
